Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1927-05-20
Abstract: 271,502. British Thomson-Houston Co., Ltd., (Assignees of Traver, O. C.). May 22, 1926, [Convention date]. Protective arrangements. - Two circuits 2, 3 are interconnected by an automatic reclosing circuit-breaker 1 opened upon overload as determined by a relay 8, either or both the circuits 2, 3 being supplied by associated sources 4, 5. The circuit-breaker 1 is normally held closed by a coil 6 energized from circuit 2 through resistor 31, contacts 26, coil 6, contacts 7 and 22 to earth. Assuming a fault occurs on circuit 3 and source 4 is the only one operative, the coil 6 is de-energized by the opening of contacts 7, which remain open for a while owing to the dash-pot 23. On the opening of the circuit-breaker 1, the circuit 3 is supplied through a load indicating resistor 10, across which there is a large voltage drop owing to the fault, therefore both relays 12, 13 pick-up. The relay 13 completes a circuit for the coils 16, 18 and 17, 19 of relay 11 from the circuits 2 and 3 to ground respectively. Coils 16, 17 are additive and coils 18, 19 are subtractive. As the fault disappears, the voltage on the circuit 3 increases until coils 16, 17 overpower coils 18, 19 and relay 11 closes its contacts to complete circuit of coil 6 through contacts 21 to ground and thus to reclose the circuit-breaker 1, whereupon the relays 12, 13 drop and the circuit of coil 6 is maintained through contacts 22. If the source 5 is also operative when the fault occurs on the circuit 3, then although the relay 12 picks-up, there is not sufficient voltage across the resistor 10 for the relay 13 to pick-up, so the relay 11 remains inactive. As this fault disappears, the energization of the relay 12 weakens until it drops and completes the normal circuit for the coil 6, whereupon the circuit-breaker 1 recloses. If the fault occurs on the circuit 2 instead of on the circuit 3, the action of the relays 11, 12, 13 is the same, but another relay 14 is energized through back contacts 24 on the circuit-breaker 1 from the sound circuit 3 sufficiently to pick-up, opening its contacts 26 and closing its contacts 25 so that the circuit for the coil 6 is from the circuit 3 through resistor 30 instead of from circuit 2 through resistor 31. When the fault on the circuit 2 is removed, the circuit breaker 1 closes and the relay 14 is deenergized. The relay 14 closes its contacts 26 before opening its contacts 25 so that energizarion of coil 6 is maintained. While both contacts 25, 26 are closed, the circuits 2, 3 are interconnected through these contacts, therefore the resistors 30, 31 are provided to prevent excess currents flowing through these contacts.

Title: Process and apparatus for the ignition of mixtures of fuel and air in explosion chambers
IPC: F02C5/12
Filed: 1933-05-10
Abstract: 405,157. Gas turbines. HOLZWARTH, H., 7, Goethestrasse, Dusseldorf, Germany. May 10, 1933, No. 13634. [Class 110 (iii).] The valve-gear of elongated explosion chambers, particularly for gas turbines, is timed so that a residue of hot gas, which may be products of combustion, or scavenging air, is trapped at the outlet end of the chamber, and presents a large surface by which the new charge is ignited. The time at which the fuel-oil is injected may be adjusted by a governor relatively to the time at which charge-air is admitted, and the period of the cycle may be varied. The explosion chamber 1 for the turbine 2 is provided with a charge-air valve 5, a fuel-oil pump 19 delivering to an injector 6, an outlet valve 9, and a scavenging-air valve 3, all of these members being actuated by pressure-oil under the control of a rotating distributing valve 25 which determines the cycle. This valve is drived by an electric motor 27, and the period of the cycle, which influences the ignition, may be varied by altering the speed of the motor. The quantity of fuel delivered at each stroke by the oil actuated plunger 19 is determined by a byepass valve 41 which is actuated by a lever 39 in accordance with the setting of the speed governor R. The governor also adjusts the upper part 29 of a sleeve surrounding the control valve 25 in order to determine the time of injection of fuel. Compressors 53, 46, which may have intercoolers, supply scavenging air through a pipe 4, and charge-air through a pipe 47. The charge-air is cooled in a heatexchanger 45. The explosion chamber is provided at the inlet end with a cooling jacket 11, and at the outlet end with a heating jacket 12. The fluid for the jacket 12 is circulated through a heat-exchanger 16 by a pump 13. The heat-exchangers 16, 45 are connected by valved pipes so that they may be worked in series or in parallel. Valves 49, 57 are provided to enable hot fluid to be supplied to heat up the heat-exchangers on starting. In a modification the heat-exchangers are heated up on starting by burning fuel in air circulated through them. A sparking-plug 10 or other auxiliary igniter may be provided. The products of combustion may be used in a heat-exchanger instead of in a turbine.

Title: Improvements in or relating to automatic temperature control of electrically heated apparatus
IPC: H05B1/02
Filed: 1942-10-02
Abstract: 563,176. Automatic control systems for electrically heated furnaces &c. SIEMENS - SCHUCKERT (GREAT BRITAIN), Ltd., and WHITE, A. B. Oct. 2, 1942, No. 13884. [Class 38 (iv)] Temperature.-A regulator automatically reduces the input of power to an electrically heated apparatus or furnace as its temperature rises until when a desired temperature is reached the input is in excess of that required to balance normal heat losses ; thereafter the regulator maintains the temperature constant by cutting off and restoring the power input as required. Differential expansion of members exposed to furnace temperature causes the pivot G of a balance arm H to rise as the temperature increases. Power is supplied through a switch K which opens intermittently when the end R of the arm H enters the path of a cam O driven at a constant speed of, say, 6 r.p.m. The ratio of "off" to "on" periods progressively increases as the temperature rises until by engaging a screw N the arm H causes complete interruption of power supply until the temperature falls below that determined by the screw. The temperature at which power reduction is to commence is determined by adjusting the axis of the cam as by a screw Q ; the characteristic curve of power reduction is determined by the shape of the cam and the relative lengths of the sides of the balance arm H. The screws N, Q may be geared together so that the temperature controlled and the temperature at which progressive power reduction commences may be simultaneously adjusted or an additional screw S may be provided providing an abutment which is moved simultaneously with the axis of the cam O. Two independent devices, controlled by the same temperature responsive element, may control power reduction and power supply. The periodic circuit opening means may comprise a rotating crank and connecting rod or a bimetal strip operated by a heater controlled by the switch K or by additional contacts thereon or by an additional timing device.

Title: Cyclo-alkanone-oximes
Filed: 1963-04-08
Abstract: Cycloalkanone oximes with 5 to 12 ring carbon atoms are prepared by catalytic dehalogenation with molecular hydrogen of strong-acid salts of the corresponding 2-halocycloalkanone oximes while dissolved in an organic solvent.  Instead of the salt, the 2halocycloalkanone oxime itself may be used together with at least the equivalent quantity of a strong acid.  The cycloalkyl ring may be further substituted, e.g. by alkyl or alkoxy. Strong acids include HCl, H2SO4, H3PO4, benzenesulphonic acid and toluenesulphonic acid.  The organic solvent may be a carboxylic acid (e.g. acetic), an alcohol (e.g. ethanol), an ester, an ether or a halogenated hydrcarbon (e.g. methylene chloride).  Suitable catalysts are the metals of Group VIII, e.g. Pd which may be used as a dispersion on active carbon or BaSO4 or as an alloy, oxide or salt.  Temperatures of 0-70 DEG  C. are mentioned. The concentration of 2-halocycloalkanone oxime is preferably from 25-50%.
